Hello

I have problem to configure USB printer (CANON ip4200) using cups.
Here are some outputs:

# usbdevs

addr 1: UHCI root hub, Intel
addr 1: UHCI root hub, Intel
addr 1: UHCI root hub, Intel
addr 1: EHCI root hub, Intel
 addr 2: iP4200, Canon

dmesg
....
ulpt0 at uhub4 port 7 configuration 1 interface 0
ulpt0: Canon iP4200, rev 2.00/1.09, addr 2, iclass 7/1
ulpt0: using bi-directional mode
...

when starting cups returns following messages:
